Description of Operation

The air control valve is placed between the respirator air supply line and the helmet breathing tube. The operator may adjust the volume of air entering the respirator. The air control valve cannot be closed completely, so the operator always has sufficient air volume for breathing and to maintain positive pressure inside the helmet.

The valve comes with a belt that adjusts to fit up to a 54-inch waist. The durable buckle can be fastened and unfastened with gloved hands.

Certifications and Approvals

The ACV is approved by NIOSH for use only with Clemco Apollo HP high-pressure Type CE supplied-air respirators (not for use with low-pressure respirators). The ACV is one component of a NIOSH-approved system; use of counterfeit parts voids the NIOSH approval. To maintain NIOSH approval, use only genuine Clemco Apollo replacement parts.
